`Wallet::new` now creates a new wallet. `Wallet::load` loads an existing
wallet. The network type is now recoverable from persistence. Error
types have been simplified.
We remove `ElectrumUpdate` and return tuples instead for `ElectrumExt`
methods. We introduce the `IncompleteTxGraph` structure to specifically
hodl the incomplete `TxGraph`.
This change is motivated by @LLFourn's comment: 794bf37e63 (r1305432603)
Added
- Wallet::sent_and_received function
- Wallet::calculate_fee and Wallet::calculate_fee_rate functions
- Wallet::error::CalculateFeeError
BREAKING CHANGES:
Removed
- TransactionDetails struct
Changed
- Wallet::get_tx now returns CanonicalTx instead of TransactionDetails
- TxBuilder::finish now returns only a PartiallySignedTransaction
This commit changes the `LocalChain` implementation to have blocks
stored as a linked-list. This allows the data-src thread to hold a
shared ref to a single checkpoint and have access to the whole history
of checkpoints without cloning or keeping a lock on `LocalChain`.
The APIs of `bdk::Wallet`, `esplora` and `electrum` are also updated to
reflect these changes. Note that the `esplora` crate is rewritten to
anchor txs in the confirmation block (using the esplora API's tx status
block_hash). This guarantees 100% consistency between anchor blocks and
their transactions (instead of anchoring txs to the latest tip).
`ExploraExt` now has separate methods for updating the `TxGraph` and
`LocalChain`.
A new method `TxGraph::missing_blocks` is introduced for finding
"floating anchors" of a `TxGraph` update (given a chain).
Additional changes:
* `test_local_chain.rs` is refactored to make test cases easier to
write. Additional tests are also added.
* Examples are updated.
* Fix `tempfile` dev dependency of `bdk_file_store` to work with MSRV

Other changes:
* The `async-https` feature of `bdk_esplora` is no longer default.
* Rename `ObservedAs` to `ChainPosition`.
* Set temporary MSRV to 1.60.0 to compile all workspace members will all
features.
